LambdaCAN* Module
(LambdaCANp, LambdaCANd, LambdaCAN)
Instruction Manual
Important Note
Due to the nature of CAN instrumentation, you cannot just physically connect a measurement
module to a bus and expect data from that module to be available. The LambdaCAN* measurement
module has to be set up to send the data required and the receiving device (ex. data acquisition
software) has to know what is being sent. The setting up of modules and the production of a .dbc file
used by the receiving device to interpret the data sent, is performed using the supplied Configuration
Tool (software) which runs on a PC.

Page 7: Configuring A Module
Configuring a Module Normally, you will be configuring a module to be used in stand-alone mode. Stand-alone mode is used when the modules are connected to a CAN bus that goes directly to a data acquisition system. In stand-alone mode, a module’s configuration is performed by selecting one of the tasks in the “Task”... - Page 8 Change Node ID: Allowable range 0x01 to 0x7F (hex). When you assign a Node ID (NID), the following CAN IDs cannot be used by any other devices on the bus: 0x00, 0x80 + NID, 0x180 + NID, 0x280 + NID, 0x380 + NID, 0x480 + NID, 0x580 + NID, 0x600 + NID, 0x700 + NID, 0x7E4, 0x7E5.

Page 9: Calibration Of The Lambda Sensor
It is recommended that they be calibrated periodically during use. How often can only be determined by your experimentation. Alternatively, the sensors can be sent to ECM for recalibration. Calibration information (both factory calibration and user calibration) for the Lambda sensor is stored in a memory chip in the sensor’s connector. - Page 10 Delta O2 Table and Delta Lambda Table The %O2 calculated by LambdaCAN* modules is denoted as “O2R” and is a wet (i.e. water taken into consideration in %O2 calculation), at chemical-equilibrium (i.e. not frozen- equilibrium) %O2 measurement (see Appendix D). The Lambda (AFR, FAR, PHI) calculated by LambdaCAN* modules is denoted as “LAMR”...
- Page 11 Similarly, sometimes users would like Lambda (AFR, FAR, PHI) readings to match other instruments such as gas-bench analyzer calculated values (ex. via Spindt or Brettschneider) or company “heritage” Lambda measurement techniques. The Delta Lambda Table (found in the task “Lambda/O2 Delta Tables”) allows to user to add a number (a “delta”) to “LAMR” calculated by the LambdaCAN* module giving the “LAM”...

Page 12: Selecting What Data Is To Be Sent (Tpdos)
Selecting What Data is to be Sent (TPDOs) Data send from LambdaCAN* modules is packaged as TPDOs (Transmit Process Data Object). Each TPDO contains two pieces of data and each module can send up to four TPDOs. All selected TPDOs will be sent at the broadcast rate. For example, if the broadcast rate is 5 ms and four TPDOs were selected to be sent, then eight pieces of data would be transmitted every 5 ms. - Page 13 Pressure sensor measured pressure (absolute) in bar PPSI P(psi) Pressure sensor measured pressure (absolute) in psi PERF Pressure error bit flags Pressure sensor bit flags (LambdaCANp only) PERC CANopen error code ECM CANopen pressure error code (LambdaCANp only) Table 2: LambdaCAN* Parameter List...

“T” (P/N 09-05). Simply attach dashCAN* to the CAN bus and parameters from two ECM *CAN modules can be displayed and converted to analog outputs (dashCAN2 or dashCAN+ only). The top display and half the analog outputs can be assigned to one module and the bottom display and the other half of the analog outputs can be assigned to the same or another module. - Page 17 When first entering SYS mode, either “MOd” will be on the top display or “LOCK” will be on the bottom display. If “MOd” is displayed, the and keys will roll through the setup options (see Table 4). First the options for the module assigned to the top display are shown on the top display, followed by identical options for the module assigned to the bottom display, ending with the global CONF (Configuration) setup.

Page 18: Mod (Module) Setup Option
MOd (Module) Setup Option In MOd setup, the serial number of the module assigned to the top or bottom display is entered. The serial number is written on a label on the module. The module assigned to the top display will be assigned the first half of the analog outputs. The module assigned to the bottom display will be assigned to the second half of the analog outputs. -
Page 19: Disp (Display) Setup Option
Here is an example of setting analog output 2 for a dashCAN+ (i.e. A2): 1. Press the SYS key so that “MOd” appears on the top display. 2. Press the key until “AOUT” is on the top display. Then press the ENT key. 3. - Page 20 1V4V (dashCAN2 and dashCAN+ only) “1V4V” commands the analog outputs to go to 1V then 4V. This is used to verify that the data acquisition system reading the analog outputs is correctly reading them. LOCK “LOCK” locks the MOd, RATE, AOUT, dISP, and LEdS setup. This stops unauthorized modification of the display.

Page 21: Using The Lambda Sensor Simulator
A properly operating LambdaCAN* module monitors lambda sensor condition and can calibrate the lambda sensor. An external pressure source is required to check out the pressure sensor. Lambda Sensor Simulators can be returned to ECM on a schedul e (1 year recommended) for recalibration. -

Page 25: Module Stand-Alone Mode And Eib Mode
Appendix B: Module Stand-alone Mode and EIB Mode CAN data from LambdaCAN* modules can either be taken directly from the modules themselves or from the CAN port of display heads connected to the modules. When data is taken directly from one or more modules, each module must in Stand-alone mode. When data is taken from one or more display heads of a Lambda 5220, or EGR 5230 analyzer, each module must be in EIB mode. - Page 26 3. Slide the PCB out. Install a jumper on JP4. Jumper 4. Make sure both O-rings are on the threaded connector. 5. Slide the PCB into the enclosure until the two tangs “click”. 6. Put the nut on and tighten ONLY ½ turn from where it is seated. If this nut is tightened too much, the connector will crack and the enclosure will not be sealed.

Page 30: Interpreting Data From Lambdacan* Modules
This fact is well documented in the literature. However, some organizations prefer to call their specific (and often unique) Spindt or Brettschneider calculations of Lambda the “true” values. To satisfy such needs, ECM has provided the Delta Lambda Table and Delta O2 Table features. - Page 31 Pressure compensation (P-comp) data is stored in the memory chip of every Lambda and NOx sensor. ECM offers P-comp kits for all of its LambdaCAN* kits. It is highly recommended that pressure compensation be used with any lean burn, HCCI, or...
- Page 32 Comparing to an ETAS LA4 Meter Many ETAS meters with new sensors will not correctly show the %O2 when the sensor is held in air. The actual %O2 in air depends on the humidity and will be almost always less than 20.945%.

Page 39: Setting Up Ati Vision For Ecm Modules
Introduction Connecting ECM LambdaCAN hardware to ATI VISION software is simple and does not require any third-party software interface. Using the ECM Configuration Tool software to produce a .dbc database file, and the ATI VISION CANMonitor interface, any available hardware CAN interface can be used to read LambdaCAN data. - Page 40 Creating a .dbc File The ECM Configuration Tool is used to create a .dbc database file for describing the CAN messages broadcast from the LambdaCAN. All ECM products with a CAN interface use the CANopen protocol at 500kHz by default. To generate a .dbc file using ECM Configuration Tool: 1.
- Page 41 ATI VISION CANMonitor provides a method of reading general purpose information from any available CAN channel. The .dbc file generated by the ECM Configuration Tool is used to describe the format of the information available to VISION. To setup a CANMonitor in ATI VISION: 1.
